Description

L'invention concerne un montage de palier sur un arbre et concerne plus particulièrement un montage de palier à corps roulants disposés entre une bague extérieure et une bague intérieure, dans lequel la bague intérieure est portée par un manchon élastique d'immobilisation de ladite bague intérieure sur un arbre.The invention relates to a bearing mounting on a shaft and relates more particularly a rolling body bearing arrangement arranged between a outer ring and an inner ring, wherein the inner ring is carried by an elastic sleeve for immobilizing said ring interior on a tree.

La publication FR-A-2217588 décrit un montage dans lequel la bague intérieure possède des portées coniques et dans laquelle s'emboíte un manchon fendu qui possède une surface extérieure complémentaire à ladite portée. L'effet de serrage du manchon au contact de l'arbre et de la bague est obtenu à la suite d'un déplacement axial du manchon.The publication FR-A-2217588 describes an assembly in which the ring interior has conical spans and into which fits a split sleeve which has an external surface complementary to said scope. The clamping effect of the sleeve in contact with the shaft and the ring is obtained following an axial displacement of the sleeve.

La publication FR-A-2662477 décrit un montage de palier pour emploi à température élevée dans lequel les bagues et les corps roulants sont réalisés en céramique. Un ensemble de cages flexibles assure le maintien du roulement et compense les dilatations thermiques radiales différentielles du support métallique du roulement.The publication FR-A-2662477 describes a bearing assembly for use at high temperature in which the rings and rolling bodies are made ceramic. A set of flexible cages maintains the bearing and compensates for differential radial thermal expansions of the metal bearing support.

L'invention a pour objet un montage de palier à sécurité augmentée susceptible d'éviter le déplacement relatif accidentel de la bague du roulement par rapport à l'arbre.The subject of the invention is an increased safety bearing assembly. likely to avoid accidental relative displacement of the ring of the bearing in relation to the shaft.

L'invention a également pour objet un montage de palier qui assure un bon centrage et l'immobilisation de la bague du roulement par rapport à l'arbre indépendamment de la température du fonctionnement du roulement, notamment lorsque les coefficients de dilatation de la bague et de l'arbre sont différents.The invention also relates to a bearing assembly which ensures good centering and immobilization of the bearing ring relative to the shaft regardless of the operating temperature of the bearing, especially when the expansion coefficients of the ring and the shaft are different.

L'invention a également pour objet un montage de palier dans lequel le roulement est monté sur l'arbre au moyen d'une douille intermédiaire solidaire dudit arbre, qui possède un moyen de réglage du diamètre extérieur de la douille au contact du diamètre intérieur de la bague du roulement.The invention also relates to a bearing assembly in which the bearing is mounted on the shaft by means of an intermediate sleeve integral with said shaft, which has a means for adjusting the diameter outside of the bush in contact with the inside diameter of the ring of the rolling.

Selon l'invention la douille possède une surface extérieure bombée dont le sommet est au contact de la surface intérieure de la bague intérieure du palier et des portées intérieures localement immobilisées au contact dudit arbre.According to the invention, the socket has a curved outer surface, the vertex is in contact with the inner surface of the inner ring of the landing and interior spans locally immobilized in contact with said tree.

Selon une autre caractéristique du montage, le coefficient de dilatation de la douille est inférieur au coefficient de dilatation de l'arbre et supérieur au coefficient de dilatation de la bague.According to another characteristic of the assembly, the coefficient of expansion of the bushing is less than the expansion coefficient of the shaft and greater than the coefficient of expansion of the ring.

Cette caractéristique crée artificiellement à la surface de la douille une portée du roulement et permet de conserver dans la plage des températures de fonctionnement du palier, un ajustement serré sensiblement constant au contact de la bague intérieure du roulement.This characteristic artificially creates on the surface of the socket a bearing capacity and keeps in the temperature range of the bearing, a substantially constant tight fit to the contact of the inner race of the bearing.

La caractéristique précitée permet également d'obtenir une liaison rigide entre la douille et une bague du roulement préservée des contraintes intérieures.The aforementioned characteristic also makes it possible to obtain a rigid connection between the bushing and a bearing ring preserved from stress interior.

La caractéristique précitée permet encore l'absorption par l'arbre et la douille de l'ensemble des contraintes qui s'exercent dans le montage.The aforementioned characteristic still allows absorption by the tree and the socket of all the stresses exerted in the assembly.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description du montage de palier, en référence au dessin annexé dans lequel :

  • la figure 1 est une demi coupe axiale du montage conforme à l'invention,
  • la figure 2 est une demi coupe axiale d'une variante de réalisation du montage,
  • la figure 3 est une représentation linéaire des variations dimensionnelles du montage sous l'effet d'une dilatation différentielle de ses constituants.
Other characteristics and advantages of the invention will appear on reading the description of the bearing assembly, with reference to the attached drawing in which:
  • FIG. 1 is an axial half-section of the assembly according to the invention,
  • FIG. 2 is a half axial section of an alternative embodiment of the assembly,
  • Figure 3 is a linear representation of the dimensional variations of the assembly under the effect of differential expansion of its constituents.

On désignera dans la suite de la description par les mêmes références, les éléments et organes du montage représentés aux figures 1 et 2.In the following description, the same references will denote the mounting elements and components shown in Figures 1 and 2.

Comme représenté aux figures 1 et 2, un palier 10 est monté dans un élément de carter 11 et porte un arbre rotatif 16. As shown in Figures 1 and 2, a bearing 10 is mounted in a casing element 11 and carries a rotary shaft 16.

Le palier 10 est un palier à corps roulants 13 disposés entre une bague extérieure 14 montée dans l'élément de carter 11 et une bague intérieure 15. Le palier 10 est monté sur un arbre 16 et une douille intermédiaire 17 solidaire de l'arbre 16 qui porte la bague intérieure 15.The bearing 10 is a rolling body bearing 13 arranged between a ring outer 14 mounted in the housing member 11 and an inner ring 15. The bearing 10 is mounted on a shaft 16 and an intermediate bush 17 integral with the shaft 16 which carries the inner ring 15.

La douille 17 possède deux portées de montage 20, 21 intérieures serrées sur l'arbre 16 par un procédé de frettage qui assure à la douille 17 une bonne qualité de centrage et d'immobilisation en rotation comme représenté à la figure 1.The socket 17 has two tight interior mounting surfaces 20, 21 on the shaft 16 by a hooping process which provides the bushing 17 with a good quality of centering and immobilization in rotation as shown in figure 1.

L'immobilisation axiale de la douille 17 sur l'arbre 16 est assuré par une extension radiale (fig. 1) d'une extrémité B de ladite douille 17 au contact d'un épaulement 22 de l'arbre 16. L'autre extrémité A de la douille 17 est liée à l'arbre par une extension qui s'étend axialement au contact d'une portée filetée 23 de l'arbre 16 (fig. 1) ou qui prend appui comme représenté à la figure 2 sur un écrou 24.The axial immobilization of the socket 17 on the shaft 16 is ensured by a radial extension (fig. 1) of one end B of said socket 17 in contact a shoulder 22 of the shaft 16. The other end A of the socket 17 is linked to the shaft by an extension which extends axially in contact with a threaded bearing 23 of the shaft 16 (fig. 1) or which bears as shown in Figure 2 on a nut 24.

Dans l'exemple représenté à la figure 1, une surface bombée est réalisée sur la douille 17 par usinage.In the example shown in Figure 1, a curved surface is produced on the bush 17 by machining.

En rapport à la figure 2, sous l'effet de la force de serrage communiquée par l'écrou 24 sur la douille 17, celle-ci est soumise à une force axiale de compression qui se traduit par une expansion radiale en son milieu et qui confère à la douille une surface extérieure bombée dont le sommet 25 est au contact de la surface intérieure 15i de la bague 15. Dans une telle configuration, les portées de montage 20, 21, de la douille sont axialement localisées de part et d'autre du plan diamétral qui contient le sommet de la surface extérieure bombée de la douille.In relation to FIG. 2, under the effect of the communicated clamping force by the nut 24 on the socket 17, the latter is subjected to an axial force of compression which results in a radial expansion in the middle and which gives the socket a curved outer surface, the top 25 of which is in contact with the inner surface 15i of the ring 15. In such a configuration, the mounting surfaces 20, 21 of the sleeve are axially located on either side of the diametral plane which contains the vertex of the domed outer surface of the socket.

Au cours du montage de l'ensemble constitué par l'arbre 16 et par la douille 17, celui-ci est placé dans la bague 15 centrée sur le sommet de la surface bombée de la douille.During the assembly of the assembly constituted by the shaft 16 and by the socket 17, this is placed in the ring 15 centered on the top of the domed surface of the socket.

Si le coefficient de dilatation du matériau constitutif de la douille est inférieur à celui de l'arbre 16, l'échauffement de l'arbre a pour effet d'améliorer le contact entre la douille 17 et l'arbre 16. If the coefficient of expansion of the material of the sleeve is lower than that of the shaft 16, the heating of the shaft has the effect to improve the contact between the bush 17 and the shaft 16.

La figure 3 illustre les variations dimensionnelles du montage sous l'effet de la température, où l'on retrouve les extrémités de fixation A et B de part et d'autre du sommet 25. Lors d'un échauffement, ces extrémités se déplacent en A1 et B1. Lors d'un refroidissement ces extrémités se déplacent en A2 et B2.Figure 3 illustrates the dimensional variations of the assembly under the effect temperature, where we find the fixing ends A and B of on either side of the summit 25. During heating, these ends are move to A1 and B1. During cooling these ends get move to A2 and B2.

Lorsque la température varie, la dilatation supérieure de l'arbre 16 par rapport à la douille 17 étire cette dernière (chauffage) et réduit la hauteur h de la surface bombée ou, au contraire resserre la douille (refroidissement) et augmente cette hauteur h.When the temperature varies, the upper expansion of the shaft 16 by relative to socket 17 stretches the latter (heating) and reduces the height h of the curved surface or, on the contrary, tightens the sleeve (cooling) and increases this height h.

Il apparaít alors que le déplacement radial du sommet 25 n'est plus directement proportionnel aux coefficients de dilatation des matériaux employés.It appears then that the radial displacement of the vertex 25 is no longer directly proportional to the expansion coefficients of the materials employees.

La dilatation radiale de la section de plus fort diamètre de la douille sera par conséquent atténuée en fonction des coefficients de dilatation respectifs de l'arbre 16 et de la douille 17, et en fonction des caractéristiques dimensionnelles de la douille, notamment la hauteur h et la longueur entre les extrémités de fixation A et B.The radial expansion of the larger diameter section of the sleeve will be consequently attenuated as a function of the respective expansion coefficients of the shaft 16 and of the bush 17, and depending on the characteristics dimensions of the socket, in particular the height h and the length between the fixing ends A and B.

Le montage précité est particulièrement adapté aux roulements en céramique dans un environnement en acier.The above assembly is particularly suitable for bearings in ceramic in a steel environment.
